When my BBcode table only contains literal pattern matches all the replacements are carried out without a problem. When my BBcode table contains:



\[b\]([^[]+?)\[\/b\] (pattern) <b>$1</b> (replacement)

no pattern matching is carried out at all, or if it is the body of the processed text is not displayed on the screen. This is so even when the body of that text only contains alphabetic characters.

I have fixed this. When the pattern is saved in forum_bbcode the back slashes are not saved with it. I don't know why this is. My work around is to use phpMyAdmin to edit the pattern directly in the database and put the back slashes back in.

Did you get the html code for a backslash something like #92;
If so the form converted it so it'd come out like a \ in html format. There's something to inject to remove this error but I'm not exactly sure.
